What are some examples of type checking in C++?

Type checking in C++ ensures that variables are used with the correct data types. For example, if you declare an integer and try to assign a string to it, the compiler will throw an error.

Can you show me a code snippet that demonstrates this?

Sure! Here's a simple example:

int number = 5;
number = "Hello"; // This will cause a compile-time error.

In this case, assigning a string to an integer variable is not allowed.

What about type casting? How does that work?

Type casting allows you to convert one data type to another. For instance:

float f = 3.14;
int i = (int)f; // This will convert float to int, resulting in i being 3.

Are there any differences between static and dynamic type checking?

Yes, static type checking occurs at compile time, while dynamic type checking happens at runtime. C++ primarily uses static type checking.
